Yeah I would have thought so, still a great price esp with uprated valve springs etc. im pretty tempted for a spare head to build up.
we're they brand new stock valves? And who carried out the 3 valve cut?
Also regarding the full combustion chamber machining, does this effect the compression ratio? Tempted to have that done!
To be honest I have no idea what it should sell for, it's just using up space in my garage, so ive just plucked a figure.
The springs and retainers alone woud be around £200, lol.
in the early days of my build parts buying I'd already bought a set of Ti retainers and valve stem seals before I bought this so I was gutted, lol.
its for sure a good base for a head build up, the valves will most likely not be new but stock with just the valve cut, this is no bad thing as the OEM valves are better the most aftermarket, only when you go Inconel on the exhaust does this trump the OEM valves. I did it for my VE head and I run upto £400 on the valves alone
I bought the block (still have it and its in the US waiting to go to Mazworx,
and the head from a guy called Toby Broadfield, he's a top guy on Zilvia and very well known (google him and check his s13 build), he bought the S15 goodies but then went LS3 (traitor). I bought them fom him via Zilvia and then containered it back from the states, i asked him at the time and he didn't now who had done the head work but he was sure that the work had been done.
personnaly if I'd not gone VE I would have gone Supertech oversized valves and a new valve job, plus all the other trimmings, so depending on how far you want to go it a good base head.
regarding the full combustion chamber, you have three options..
nothing, so retain both quench pads
Hemi (didn't know what this actually meant until recently, Hemi being one quench pad is machined out)
Full (both quench pads machined out, so Full Circle combustion chamber)
i have to confes that I don't know anywhere in the UK that performs CNC machining on SR20 heads, if anyone knows let me know.
Its a very technical argument as to what shape your combustion chamber shoud be, I'd decided on Full as Mazworx offer this in both 86 and 90mm, but if id not been in the US I would have probably sent it to Naprec in Japan (same people that build Suzuki motor) and had there beautiful CNC Full combustion chamber with Beryllium copper valve seats, erm....
Wth the Full you can run loads of boost with little worry about detonation. Couldn't tell you why off hand, but all the top SR20 motors are sporting Full Circle chambers. Mazworx 1400hp S15 drag and under Suzuki now 1000hp time attack monster both sport Full circle chambers to name a few.
and yes compression ratio is effected, always lowering the ratio, but you can change this at will with the head gasket size to keep the same as before the machining or lower further etc.
Bugger, forgot this was a sales thread, lol
